Grade 1 cylindrical locks are cycle-tested to 800,000 operations; free-wheeling clutches let the outside lever turn without stressing the mechanism when locked, so forced turning cannot break the lock.
Functions
Every series offers the standard functions – passage, privacy, office/entry, classroom, storeroom, store door, communicating and more – so one family of locks covers the whole building and keys to one master key system.
Fit
Locks fit the standard ANSI 161 cylindrical and 86 mortise preparations of WS hollow metal doors, 2¾ in backset, 1⅜ – 2 in doors, with ASA strikes.

常见问题
Cylindrical or mortise?
Cylindrical locks install in a simple bored preparation and suit most doors. Mortise locks sit in a pocket in the door edge, are stronger and offer more functions – the choice for main entrances and maximum-duty doors.
